Description

The present invention relates to a nameplate device, and more particularly to a nameplate device having a structure in which a character portion that functions as a nameplate is lit by detecting contact or approach of a human body.

In general, a nameplate showing the resident's first and last name, address, name, etc. is displayed near the entrance / exit of a building such as a house or a business establishment (for example, an entrance door, an outer wall beside the entrance, a gate pillar, etc.). Such a nameplate is originally provided for the purpose of making it possible to grasp the first and last name of a resident from the outside of the building, and is attached to a relatively conspicuous place near the entrance and exit of the building (for example, a patent). Reference 1).

JP-A-2015-125171

However, such conventional nameplates have the following problems, and improvement thereof has been desired.

In other words, due to the growing awareness of personal information protection in recent years, there is a growing demand for not disclosing the first and last names and addresses of residents of buildings (especially first and last names) to unrelated third parties. An increasing number of users do not like nameplates that prominently display their first and last names and addresses.

On the other hand, the nameplate is an important means for mail carriers and courier companies to confirm the delivery destination of mail and parcels, so the nameplate has a great significance. In particular, in recent years, when mail-order sales tend to be used more frequently, nameplates are becoming more important as a means for visitors such as mail carriers to confirm the surnames and addresses of residents of buildings.

The present invention has been made in view of such problems, and an object of the present invention is to provide a nameplate device capable of displaying a first and last name, an address, etc. only for visitors who have business. There is.

The control unit is characterized by having a control configuration for turning on the light source and irradiating the back surface of the surface plate with light when the detection signal from the sensor is received.

In this nameplate device, when the sensor detects the contact or approach of the human body to the surface plate, the light source of the light guide plate provided on the back surface side of the surface plate is turned on based on the detection signal. As a result, the back surface of the surface layer plate is irradiated with light from the light guide plate, and the light is transmitted through a light-transmitting portion that imitates a character that functions as a nameplate formed in the light-shielding layer of the surface layer sheet. Characters are displayed brightly on the surface of. At this time, since the light transmission of the portion other than the characters is blocked by the light-shielding layer, the pattern and / or the pattern formed by the colored layer on the surface layer sheet are displayed as they are.

In this nameplate device, the light source of the light guide plate is off when the sensor does not detect the contact or approach of the human body to the surface plate, so that the surface of the surface plate is patterned and / or colored. The patterns and colors formed by the layers are displayed as they are. That is, when the contact or approach of the human body is not detected, only the pattern or coloring formed by the pattern and / or the colored layer is displayed on the surface of the surface layer plate.

The nameplate device according to the present invention has the following configuration as a preferred embodiment.

Embodiment 1
As shown in FIG. 1, the nameplate device 1 according to the present invention does not display characters that function as nameplates such as first and last names when there are no visitors, and displays characters that function as nameplates only when there are visitors. A main body to which a surface plate 3 to which a surface sheet 2 is attached, a light guide plate 4 having a constantly extinguished light source that irradiates the surface plate 3 with light, and a surface plate 3 are mounted. The case 5, the sensor 6 that detects the contact or approach of the human body to the surface plate 3, the control unit 7 that controls the lighting of the light source of the light guide plate 4 based on the detection signal 6 of the sensor, and the main body case 5 to be mounted. A fixing bracket 8 for fixing to is provided as a main part (see FIG. 3).

The surface layer sheet 2 is in the form of a thin sheet (or thin plate) having a multi-layer structure that appears to have been patterned and / or colored when viewed from the surface in a normal state (when the light guide plate 4 described later is not lit). It is composed of members. The surface sheet 2 includes at least a patterned and / or colored layer and a light-shielding layer formed on the back surface side of the patterned and / or colored layer to block the transmission of light. In normal times, the pattern or coloring formed by the patterned and / or colored layer is visible from the surface side of the surface layer sheet 2. The layer in which the pattern and / or the color is applied is configured to be thin or transparent enough to allow light to pass through.

Then, a translucent portion imitating characters (for example, first and last name, address, first name, etc.) that function as a nameplate is formed at a predetermined position of the light-shielding layer, and when the light guide plate 4 described later is lit, the light guide plate 4 is used. The emitted light passes through this translucent portion and appears visibly on the surface of the surface layer sheet 2. The light-transmitting portion is formed by cutting out a light-shielding layer at a position corresponding to a character or forming a light-shielding layer at a position corresponding to a character thin enough to allow light to pass through.

In the present embodiment, a metal-like resin sheet material (trade name "METALFACE") manufactured by Gikkodo Co., Ltd. is used as the surface layer sheet 2. This metallic resin sheet material has a structure as shown in FIG. 4A or FIG. 4B, and any one of these sheet materials is preferably used as the surface layer sheet 2.

That is, the sheet material shown in FIG. 4A is a type of sheet material in which the resin transparent base material 200 is exposed on the sheet surface, and is formed on the back surface side of the transparent base material 200 with a transparent ultraviolet curable ink. The metal pattern layer 201 is provided. The metal pattern layer 201 is formed with an uneven pattern (metal pattern) by transferring the metal surface to a surface that does not come into contact with the transparent base material 200 (non-contact side). The transparent base material 200 and the metal pattern layer 201 form the first layer portion of the surface layer sheet 2.

Then, one surface of the first layer portion, in the example of FIG. 4A, the metal color ink constituting the second layer portion on the back surface side (the side where the uneven pattern is formed) of the metal pattern layer 201. The formed metal color layer 202 is formed. As described above, the sheet material shown in FIG. 4A has a metallic tone (a state in which the metal pattern and the metal color are combined) when viewed from the surface side by superimposing the metal pattern layer 201 and the metal color layer 202. Is to be presented. In the following description, when referring to a sheet body composed of a first layer portion and a second layer portion, this may be referred to as a multi-layer sheet body.

Further, in this illustrated example, in order to impart a color (hue) other than a metallic color such as brown, yellow, or red to such a metallic sheet material, the back surface side (specifically,) of the metallic color layer 202 is given. Formes a colored transparent colored layer 203 (between the multi-layer sheet body and the light-shielding layer 204 described later). As a result, colors such as brown, yellow, and red are added to the metallic tone when viewed from the surface side. Since the colored layer 203 is provided to give the sheet material a color other than the metallic color, it can be omitted when the sheet material is composed of only the metallic color.

A light-shielding layer 204 is further formed on the back surface side of the colored layer 203. The light-shielding layer 204 is a layer for preventing light emitted from the back surface side (colored layer 203 side) of the sheet material from passing through the metal color layer 202 and escaping to the front surface of the sheet material, such as black ink. It is made of a light-shielding material such as a black sheet. Then, at a predetermined position of the light-shielding layer 204, a translucent portion imitating the character functioning as the nameplate described above (see the character portion of "Takahashi / TAKAHASHI" shown in FIG. 2B in this embodiment) is formed. It is formed.

On the other hand, FIG. 4B shows a modified example of the sheet material shown in FIG. 4A, and this sheet material is a type of sheet material in which the uneven pattern of the metal pattern layer 201 is exposed on the sheet surface. In this sheet material, the transparent base material 200 side of the first layer portion is used as the back surface side, and the metal color layer 202, the coloring layer 203, and the light-shielding layer 204 are formed on the transparent base material 200 side. It is different from the sheet material shown in 4 (a). In this sheet material, an uneven pattern formed by transferring the metal surface appears on the surface of the sheet material, so that even the feel of the metal surface is reproduced. Since other configurations are the same as those in FIG. 4A described above, detailed description thereof will be omitted.

The surface layer plate 3 is formed by attaching the surface layer sheet 2 configured in this manner to the attachment base plate 9. FIG. 5 shows an example of the appearance configuration of the sticking base plate 9. The sticking base plate 9 is made of metal (for example, corrosion resistance of stainless steel or the like) having an opening 9a in the center and a sticking margin portion 9b for sticking the outer periphery of the back surface side of the surface layer sheet 2 around the opening 9a. It is made of high metal plate material. In the present embodiment, a rectangular opening 9a is punched out in the center of a substantially rectangular metal plate, and the outer peripheral portion of the opening 9a on the surface side is thinly carved by etching or the like according to the shape of the surface layer sheet 2. A dented state is formed by the above, and the dented state is designated as a sticking allowance portion 9b. The opening shape and opening position of the opening 9a are determined so that at least a light-transmitting portion imitating a character that functions as a nameplate on the surface sheet 2 is arranged inside the opening 9a.

Further, in the present embodiment, the outer peripheral edge 9c on the surface side of the sticking base plate 9, in other words, the outer side (hatched portion in FIG. 5) of the thinly carved sticking allowance portion 9b is mirror-finished to provide a design. The effect is being improved. Further, in the attached base plate 9 shown in the drawing, a part of the outer peripheral edge portion 9c (specifically, near the center of the lower edge) is formed so as to project inward, and the projecting portion 9d protruding inward will be described later. It functions as a sensor electrode 6b of the sensor 6.

The light guide plate 4 is a light guide plate for irradiating the opening 9a of the surface layer plate 3 with light from the back surface side, and includes a light source (not shown) that is always turned off. Specifically, the light guide plate 4 has a shape dimension corresponding to the opening shape of the opening 9a of the sticking base plate 9, and is configured to fit into the opening 9a (see FIG. 3). ). More specifically, as the light guide plate 4, for example, a light guide plate in which an LED tape light serving as a light source is arranged on the end face of a resin plate that uniformly emits light from the end face is adopted. To. Further, although not particularly shown, the light guide plate 4 has a waterproof structure. The LED tape light that serves as the light source of the light guide plate 4 is electrically connected to the control unit 7 described later, and the control unit 7 controls lighting / extinguishing (lighting control).

The main body case 5 is a housing for accommodating the control unit 7 and attaching and fixing the surface layer plate 3 and the light guide plate 4 described above, and is a metal having a substantially tubular shape (rectangular tubular shape in the illustrated example). It is composed of members made of. A receiving metal fitting 13 for mounting a base mounting plate 10 for fixing electronic components and the like constituting the control unit 7 is attached to the inner wall of the main body case 5, and the base mounting plate 10 is attached to the receiving metal fitting 13. Is mounted and fixed (see FIG. 3).

In addition to the role of fixing the electronic components of the control unit 7 described above, the board mounting plate 10 also has a role of pressing the light guide plate 4 described above against the surface layer plate 3 to fix the electronic components and the like. That is, the surface layer plate 3 is mounted and fixed to the surface side end portion of the case body 5, but at that time, the light guide plate 4 is fitted into the opening 9a between the surface layer plate 3 and the base mounting plate 10. It is designed to be fixed and held by. When the surface layer plate 3 is attached to the case body 5, a sealing material 14 is interposed between the two to prevent rainwater and dust from entering the case body 5 from these joints. ..

The sensor 6 is a sensor that detects the contact or approach of the human body to the surface plate 3, and in the present embodiment, the capacitance switch that detects the contact with the human body is adopted. That is, the protrusion 9d formed on the sticking base plate 9 is used as the sensor electrode (detection panel) 6b of the capacitance switch, and the capacitance between the sensor electrode 6b (to be exact, the sticking base plate 9) and the human body is used. A sensor body 6a for detecting a change in capacitance is mounted and fixed to a board mounting plate 10. When the sensor body 6a detects the contact of the human body with the sensor electrode 6b, the detection signal is input to the control unit 7.

The control unit 7 is a control device that controls the lighting of the light source (LED tape light in this embodiment) of the light guide plate 4 based on the detection signal from the sensor main body 6a, and the control unit 7 is also attached to the board mounting plate 10. It is mounted and fixed. Although not particularly shown, the control unit 7 supplies electric power to various electronic components (for example, the electronic circuits constituting the control unit 7 and the light source of the light guide plate 4) provided in each part of the nameplate device 1. There is also a power supply circuit for this.

Then, when the detection signal is input from the sensor main body 6a, the control unit 7 controls to turn on the LED tape light, which is always off, for a certain period of time (for example, about several seconds to a dozen seconds). As a result, the light guide plate 4 emits light, and the surface layer plate 3 (specifically, the surface layer sheet 2) whose back surface is irradiated with light by the light emission of the light guide plate 4 has a light-transmitting portion (as a nameplate) formed on the light-shielding layer 204. Since only the functioning character part) transmits light, the character part (see the character part of "Takahashi / TAKAHASHI" in FIG. 2B) that functions as a nameplate is displayed brighter than the surroundings on the surface of the surface plate 3. Will be done.

The fixing metal fitting 8 is a metal fitting for mounting and fixing the main body case 5 to the mounted surface W, specifically, the wall surface on which the nameplate device 1 is mounted, and in the present embodiment, the case main body 4 can be accommodated. It is composed of metal (for example, aluminum) members. More specifically, as shown in FIG. 3, it has a substantially tubular shape with at least the front surface side open so that the case main body 5 can be accommodated together, and the main body case 5 is fitted inside from the opening 8a on the front surface side. It has a structure that can be fixed in a state of being. In this embodiment, a case is shown in which a plurality of fins (heat dissipation mechanism) 8b for heat dissipation for releasing heat trapped in the case main body 5 are provided on the outer periphery of the fixing bracket 8. These heat dissipation fins 8b can be omitted as appropriate. Further, for example, in the case where the fixing metal fitting 8 is formed in a substantially plate shape and the back surface side end portion of the case main body 5 is fixed, the case main body 5 may be provided with a heat dissipation mechanism.

Next, a usage mode of the nameplate device 1 configured in this way will be described with reference to FIG.

A: Normal time During normal time when there are no visitors, as shown in FIG. 1A, nothing is touched on the sensor electrode 6b of the nameplate device 1, and the capacitance detected by the sensor electrode 6b changes. Therefore, the detection signal is not output from the sensor body 6a. Therefore, the control unit 7 keeps the light off state without turning on the LED tape light which is the light source of the light guide plate 4, and the metal pattern layer 201 is on the surface of the nameplate device 1, that is, the surface of the surface layer sheet 2. Only the metallic pattern formed by the metal color layer 202 and the metal-like pattern (including the color imparted by the colored layer 203 when the colored layer 203 is formed on the surface layer sheet 2) is displayed and functions as a nameplate. No characters are displayed. That is, normally, the first and last name, which is the personal information of the resident, is not displayed on the nameplate device 1, and the personal information of the resident is protected.

B: At the time of visit On the other hand, when there is a visitor, as shown in FIG. 1 (b), the visitor is asked to touch the sensor electrode 6b exposed on the surface of the nameplate device 1. When the visitor touches the sensor electrode 6b, the capacitance detected by the sensor electrode 6b changes, so that the detection signal from the sensor body 6a is output to the control unit 7. The control unit 7 to which the detection signal is input controls the LED tape light, which is the light source of the light guide plate 4, to be lit for a certain period of time, so that the light guide plate 4 emits light, thereby transmitting light formed on the light shielding layer 204. Due to the light transmitted through the portion, the characters corresponding to the translucent portion (in the illustrated example, the characters "Takahashi / TAKAHASHI") are bright and bright on the surface of the nameplate device 1, that is, the surface of the surface layer sheet 2. It is easily visually displayed, and after a certain period of time, the character disappears from the surface of the nameplate device 1 and returns to the normal state. Therefore, the visitor can easily know the first and last name of the resident by touching the sensor electrode 6b, but after the confirmation of the first and last name is completed, the nameplate device 1 does not require any further operation by the visitor. Automatically returns to the state of protecting personal information.

As described above, according to the nameplate device 1 according to the present invention, when the sensor 6 detects the contact of the human body with the surface plate 3, the characters functioning as the nameplate are brightly displayed on the surface plate 4, while the contact with the human body is caused. When the sensor does not detect, only the pattern and coloring are displayed on the surface plate 4, so that when there are no visitors, the nameplate device 1 that is simple and has an excellent design is provided, and the resident's personal information (first name, last name, address, etc.) While protecting the name, etc.), when there is a visitor, it is possible to display characters that function as a nameplate and convey the resident's first and last name to the visitor. Therefore, the personal information of the resident can be disclosed only to the visitors who have business in the building.

Embodiment 2
Next, a second embodiment of the present invention will be described with reference to FIG.
The nameplate device shown in FIG. 6 is a modified example of the nameplate device 1 shown in the first embodiment, and the sensor 6 is an infrared sensor (as a sensor 6) that detects the approach of the human body instead of the capacitance switch that detects the contact of the human body. (Not shown) is shown. Since the other basic configurations are the same as those in the first embodiment, only the differences will be described, and the parts having the same configuration will be designated by the same reference numerals and the description thereof will be omitted.

In this embodiment, since an infrared sensor (for example, a pyroelectric infrared sensor) is used instead of the capacitance switch, the sensor electrode 6b of the surface layer plate 3 is omitted. Then, a light receiving element of an infrared sensor (an element provided with a pyroelectric body that receives infrared rays radiated by a human body) is provided on the surface of the surface layer plate 3, and the light receiving element is used to attach the nameplate device 1 (surface layer plate 3). It is configured to detect the approach of the human body. When the light receiving element detects the approach of the human body to the nameplate device 1, the light receiving element outputs the detection signal to the control unit 7. The control unit 7 controls the lighting of the LED tape light based on the detection signal, which is the same as that of the first embodiment.

When an infrared sensor is used instead of the capacitance switch in this way, the sensitivity of the infrared sensor and the mounting position of the infrared sensor (that is, the front tag device 1 are installed so as not to erroneously detect the approach of the human body. Adjust the height position) as appropriate. For example, as shown in FIG. 6, by selecting a sensor having a sensitivity such that the detection distance L1 in the horizontal direction by the infrared sensor is within 1.5 m, it is possible to prevent erroneous detection of a vehicle running on the road. Further, it is preferable that the height position L2 where the nameplate device 1 is installed is set to about 1.4 m from the ground to prevent erroneous detection of a small animal shorter than a human being.

Embodiment 3
Next, a third embodiment of the present invention will be described with reference to FIG.
The nameplate device shown in FIG. 7 is a modified example of the nameplate device 1 shown in the first embodiment, and in this embodiment, the case where the nameplate device 1 and the slave unit of the intercom are integrally combined is shown. Since the other basic configurations are the same as those in the first embodiment, only the differences will be described, and the parts having the same configuration will be designated by the same reference numerals and the description thereof will be omitted.

In this embodiment, when the nameplate device 1 and the intercom slave unit are combined, the slave unit unit 15 constituting the intercom slave unit is arranged adjacent to the nameplate device 1. Along with this, the surface layer plate 3 has been changed to a horizontally long rectangular shape so as to cover the surface side of the slave unit portion 15 of the intercom. Further, the main body case 5 can accommodate the internal mechanism of the nameplate device 1 (for example, the sensor main body 6a and the control unit 7) and the internal mechanism of the slave unit 15 (for example, a microphone, a speaker, an amplifier circuit, etc.). , Like the surface layer plate 3, it has been changed to a horizontally long substantially rectangular tubular shape. When the nameplate device 1 and the slave unit 15 of the intercom are combined in this way, the structure for displaying the characters functioning as the nameplate on the nameplate device 1 side in the lit state is the same as that of the first embodiment. Further, the structure of the intercom combined with the nameplate device 1 in the present embodiment, that is, the point that the master unit of the intercom is provided in the building, the communication method between the master unit and the slave unit 15, and the like are known. Therefore, detailed description here will be omitted.

It should be noted that the above-described embodiment merely indicates a preferred embodiment of the present invention, and the present invention is not limited to these, and various design changes can be made within the scope of the present invention.

For example, in the above-described embodiment, the case where the first and last name (specifically, the Kanji notation and the European character notation of the first and last name) is used as the character that functions as the nameplate is shown, but if the character functions as the nameplate, the first and last name Characters other than the above, for example, characters representing an address, may be configured to be displayed in a light emitting state in the same manner as the first and last name.

Further, in the above-described embodiment, the case where the surface layer plate 3 is formed in a substantially rectangular shape is shown, but the shape of the surface layer plate 3 is not limited to a rectangular shape, and the design can be appropriately changed, for example, an elliptical shape or a cloud shape.

Further, in the above-described embodiment, the case where a sheet material exhibiting a metallic tone in terms of surface appearance is used as the surface layer sheet 2, but for example, instead of the transfer of the metal surface in the metal pattern layer 201, a geometric pattern or a geometric pattern or the like is shown. By forming a concavo-convex pattern consisting of other figures, a pattern other than the metal pattern can be displayed on the surface, or the metal color layer 202 can be changed to a layer having a color other than the metal color to display a pattern other than the metal color. Color can be displayed. It is also possible to use a sheet material that displays only the pattern or only the color by omitting either the metal pattern layer 201 or the metal color layer 202.

Further, in the third embodiment described above, the case where the nameplate device 1 and the slave unit of the intercom are combined is shown, but in the nameplate device 1 according to the present invention, an instrument other than the intercom, for example, a mail item or a newspaper, is posted. It is also possible to combine it with a mail box or the like. When combined with a mailbox, for example, the sensor 6 may be configured to detect the opening / closing operation of the mailing lid provided on the mailbox. That is, the sensor 6 can be configured to detect the approach of the human body by opening and closing the lid of the mailbox.
